Application filed February 11, 1908. Serial 17o. M5372 its escapement mechanism.

Said invention consists of the features of construction, arrangements ofparts and com.- binations of devices to be hereinafter described and claimed. a

In the drawings, Figure 1 is a vertical typewriting machines embodying my invention, some of the parts unnecessary to an understanding of my invention being omitted. Fi 2 is a vertical transverse sectional view of t e saine taken on a line rx of Fig. 1 and looking in the direction of the arrow at said line. Fig. 3 is a horizontal sectional view of the parts shown in Figs. 1 and 2, the section being taken on the line g of Fig. 1 and looking in the direction of the arrow at said line. Fig. 4 is a fragmentary top plan view 0f.a supporting bar and the carriageretarding devices supported thereby. Fig. 5 is an enlarged detail longitudinal sectional view of the rotary device for controlling the speed of the carriage-and the drum within which it is mounted. Fig. 6 is an enlarged detail fragmentary erspective view of the column stop bar and some of the associated parts. Fig. 7 is a detail perspective view with parts broken away of the cover plate for the reed frame. F ig. S is a like view of the reed frame with the reeds mounted therein. Fig. 9 is an enlarged detail fragmentary side or face view showing the opposite end of the column stop, bar from that shown. in Fig. 6 together with the {means for supporting and effecting an adjustment of the bar. Fig. 10 is a fragmentary sectional view corrcspond ing to Fig. a but showing another form of construction.

. The frame f the machine comprises side plates 1 fronlihnd rear cross plates 2 and end corner posts 3 which support a top plate 4.

balls 7 which likewise cooperate with oppositely disposed grooved carriage rails 8 and 9 which form part of a carriage truck IO-that supports a superposed carriage structure comprising side plates 11 connected by parallel links 12 with a platen frame 13 which supports a cylindrical platen 14.

So far as the present invention is concerned the carriage may be of any suitable construction; that shown in the present instance being similar in some respects to that disclosed and claimed in my application Serial No. 362,734, filed March 16th, 1907. Depending cars 15 are formed on the carriage truck and three arm levers 16 are pivoted to these lugs at 17. The forwardly extending arms 18 of the levers co-act with screw stops 19, whereas the rearwardly extending arms 20 cooperate with downwardly pressing leaf springs 21 (see Figs. 1. and 2) which are secured to the truck by screws 22. The depending arms 23 of said levers are connected to a horizontally disposed feedrack 24 by screws 25. The construction is such that in the normal position of the parts the arms 18 of the lever 16 are forced into contact with the screw stops 19 as shown in Fig.1 by pressure of the springs 21. This carriage release mechanism is shown and claimed in my application Serial No. 415,373, filed February 11th, 1908.

The printing mechanism may be of any suitable construction, that shown in the present stance being of a general character such as that shown in the application of A. 2 W. Smith, Serial No. 295,801, filed January The various parts of the printing instrumentalities are mounted in an auxiliary frame 26 which H Cl6tfi.CllFtl)lY secured to the main frame of the machine. Key levers 27 are pivoted on-a pivot rod 28 connected at its ends to rearwkvbllly extending arms 29 of the auxiliary frame 26. Each of these key levers is provided with a finger key 30 and is guided at its forward end in. a saw-kerf or slot 31 formed in the vertically disposed. side or member of an angular plate 32 which is bent rearwardly to form a horizontally disposed. portion 33 provided with an u wardly bent flange 34 at its rear edge by W1l0l1 the angular plate is secured in the auxiliary ed at 36 to a link 37 pivoted to a bell crank lever 38 supported by a hanger 39 on a segment 40 which forms part of the auxiliary frame. A rearwardly projecting link 41 extends from the upright arm of.the bell crank rearwardly to a driver 42 pivoted at 43 on a hanger 44 secured to a segment 45 which is carried by the auxiliary frame 26. The driver 42 is pivoted at 46 to a type bar 47. The forward end of the type bar is pivoted at 48 to a guide link 49 which in turn is pivoted at 50 on a pivot wire which is seated in a groove in a segment 51, each guide link 49 working in a radial slot 52 cut in the segment 50. A depression of a key lever 27 effects an actuation of the corresponding driver 42 which effects a movement of the type bar from the normal position where the-types rest against an ink pad to the operative or printing position, during which movement the lowercase type will follow a path indicated by the dotted line a in Fig. 1.

The angular plate 32 hereinbefore referred to is provlded with a series of guide openings 53 (see Fig. 3) in the top or horizontally disposed portion 33 thereof. These openings receive the key stems 54 of denominational tabulator keys 55 and guide them in their vertical movement. The lower ends of the key stems 54 are guided in similar openings in an-angular plate 56 securedat its ends to the frame of the machine by screws 57. It will be seen from this construction that the row of denominational tabulator keys are arranged in the keyboard of the machine and constitute the last row or bank thereof.

A series of angular denominational levers 58 are pivoted and extend beneath the printing key levers as shown in Fig. 1 and each of the. levers 58 extends at its forward end through an opening in the associated key stem 54. The levers 58 all extend rearwardly, and for a short distance are parallel with each other and then flare inwardly toward each other and toward the center of the machine where they are bent at 59, thence extending rearwardly and upwardly, forming upright parallel members 60 provided at their upper ends with denominational stop ortions 61 so that each lever 58 comprises a horizontally disposed portion and an upwardly and rearwardly extending portion 60 provided at the upper end thereof with the stop member or portion 61. The various levers 58 are supported on a pivot rod 62' which passes through depending flanges 63 formed on or connected with a cross bar 64 that is sup orted at its ends upon inwardly extending ugs 65 which project from the side plates of the main frame. T his cross bar is secured to lugs by screws 66. The pivot rod 62 is secured in its bearing by screws 62 The depending supporting portion 63 of the cross bar 64 is formed with slots in which the levers 58 are received and in which they work, thus maintaining the 65 levers properly spaced apart at those porthe levers 58 extend as they pass through the slots between the reed bars.

A cover or cap plate 71 is provided with depending ends and sides 72, the sides abut ting the ends of the reed bars and that portion of the frame in which they are seated. A top 73 of the cap or cover plate bears on top of the reed bars, thus formin a means for preventing a displacement o the reed bars on the frame 70 on which they are carried. Screws 74 (Fig. 2) extend thro h openings 75 and 76 in the corners of the cover plate and frame 70 respectively and take into threaded openings in the top plate 4 of the machine so that the same screws 74 which secure the cap plate or cover in place also secure the frame 70 in place. The cover plate has a rectangular central opening 77 therein which, when the cover plate is in place, is substantially coincident with the central rectangular opening in the frame 70.

A like rectangular opening 78 is formed in the top plate coincident with the rectangular openings in the frame 70 and cover plate 71 so that the stops 61 or their actuating levers may extend through the coincident openings in the top plate, in the frame 70 and in the cover plate 71, and are guided in the slots 67 between the reed bars 68 in the movements of the stops toward and from the front of the machine. By this construc tion the parts can be readily assembled and yet undivided bars 68 are provided between the denominational stop levers and strong and rigid means are provided to resist thedenominational stops when an impact of the carriage against said stops takes place.

Each denominational key lever is connected to one end of a contractile spring 79 (Figs. 1 and 3). and the other end of said spring being conncctcd at 80 to an angular plate 81 secured to the roar cross plate 2 of the machine by rivcts S).

Brackets S3 and 8-1 \Fig. 2) are secured by screws 85 to upwardly projecting lugs 86 on the carringc truck. The brackets 83 and 84 constitute bearings and supports for a column stop bar 87 grooved on opposite sides as at 88 for cooperation with bifurcated platelike column stops 89. The right hand bracket 84 as shown in Fig. 6 is provided with an inclined angular opening or seat 90 for cooperation with an angular portion 91 of the column stop bar to prevent said bar from turning in its bearings and to maintain the stop bar and the stops carried thereby inclined on the carriage as shown in Fig. 1 A-cylindrical stemor: extension 92 is received a'correaponding opening.- in.r.-the bracket 84. lihe nppositeendioftheicolumn stop her asshowminFig. 9 is provided with a i threaded and Q which passesfreely through an openingin ithe'bracket 83randis provided with a nut 94 on rtheouter side of the-bracket F seen that :eachof the column stops89- is pro vided wi-th a forwardlyextendingprojection lori abutment 96 against which the lower edge .of a locking plate97 is adapted to bear. This locking plate ispivot'ed to brackets'83 and 84 as indicated at 97 so that it may beswung forwardly when desired to carry the lower free ehdor edge ofrthe locking plate away. from the abutments 96 on; the column stops and enable themto be detached-from the stop rod. W'hcn, however, the locking plate is in the position shown in Figs; 1' and 6 it prevents a detachment of any of the/column stops. 99 to :the loc ingbar to facilitate a movement of the looking bar to the inoperative position, whereas a coiled spring 100 (see Fig. 2) is operative to move .the locking bar to the operative or locking position. 7

From the foregoing-description it .will be understood that a depression of any of the denominational keys 55 will move the corresponding denominational stop filupwardly and forwardly in an inclined path or are of which the pivot 62 is the center-and into the path of the stopping portion 10]. of the column stops carried by the carriage.

In order to effect a release-of the carriage by an actuation of any of the denominational keys and at the same time to automatically throw the means for controlling the speed of the carriage into operation, I provide a universal bar 102 which extendsbeneath the forward ends of the levers 58 as shown in Figs. 1 and 3. This universal bar is formed with rearwardly projecting side members 103 which are riveted-at 104 to forwardly projecting arms 105 formed a part of a cross bar or member 106. .--The arms-105 are pivoted at 107 to forwardly projecting lugs or brackets 108 connected to or formed on the cross bar 04 hereinbefore referred to. The right-hand arm 105 is extended rearwardly to form an arm 109 which is connected to the lower. end of an upright link 1.10 (see Figs. 1

(i0 and 2). Said link is connected at its upper end to a crank arm 111 (see Figs. 1, 2 and 4) projecting from the rock shaft 112 which carries and may be formed as apart of a drum 113. The rock shaft 112 is supported at its or ends by c oned bearing studs114 Whichexosition.

A fingpr piece 98 is secured by screwsi :tend through openingsiinrdepending lugs-.115 rithat project from across harililfisnpported at :itsie'nds roux-inwardly extendinglugs F117 isthatnproj'ect from- ;the side .plates 110i xithe machine and are secured.theretoibycscrews 118. wlhe drum .113 iswshownainudetaili-in Fig- 5 and is internally threaded .ati1-19for cooperation with external threadson a cap or cover 120 provided with a flange 120P- received within the drum.

The drum and cap formanzinclosed chamber in which a rotary. .carriage-speedmontrolling device. is contained. ..Th.1sv device comprises a shaft 121 which :rotatesin aibearing sleeve 122 formedas apart of the drum and has'crossedblades, wings or:arms.123 secured thereto. The-upper end ofthe shaft 121 which extends beyond the sleeve122has a pinion.1-24-secured thereto by a pin 125 which extends through the hubof the-pinion and throughsthe-shaft .121. Any suitable material may be contained within. the drum such, for instance, as plumbago and shot or shot alone. JIh'e sleeve'122 1s providedat its outer end with an off-set arm 126 (see Fig. 4) to which anarm or finger 127 is secured by a screw 128. The contact face of the arm or finger127 is adapted to-bear against the ends-of the teeth-of the carriage feed rack 24 so that when the drum, which is pivoted at substantially right angles to the axis of rotation of therotary device, is swung to the operative position the finger forces the feed rack around its pivots 17 and out of mesh with a feed pinion 129 which is operatively connected wlth suitable escapementanechanism (not shown), thereby releasing the carriage from its escapement mechanism. The relation of the arts is such that the same movement which effects a disengagement of the rack from its'feed pinion also carries the pinion 124 into mesh with the feed rack and controls the depth of engagement between the teeth of the feed rack 24-and the pinion 124. The carriage rack being released in the manner described .is brought into mesh with the pinion 124 which is rotated by the power of a spring drum 13.0 connected to the carriage by a cord 131 and the rotary device within the drum is turned and a retarding effect is produced to control the s eed of the carriage in its movement in the irec-tion of its feed movement when the tabulating mechanism is actuated and the carriage is free from its escapement mechanism.

In Fig. 10 I have shown another form of construction of carriage retarding device which is mounted and controlled-in the manner hereinbefore described. It is the same as the structure formerly-described except that the cap orcover 120 has a shorter flange and the cap may be adjusted farther in the drum 113 in order to exert more or less pressure on the mass of material contained within the drum and thus offer more 18 0 "or less resistance to the turning movement of scribed to drum ahea forced through the material.

arms 1123? which do not extend from edge to edgle substantially to the walls of the drum an o" as in the structure previously deush the mass of material in the of them but the arms 123 are The shaft 121 in Fig. does not extend so far through the drum in *one direction.

5:. and carrie 7 drum as in the previously described struc- 10 ture and is provided with a collar 122 to prevent the withdrawal of the shaft from the cross bar 1 16 so that this spring is flexed when the drum is swung on its pivots to release the carriage and restores the drum to normal position when pressure on a tabulator key is released.

From the fore oing description it will be seen that the pul l of the spring drum is exerted on the carriage about centrally thereofv and about centrally between the bearings for the carriage where the pull is most efiective and buckling or side strain on the bearingsof the carriage is avoided; that the feed rack is likewise located between the carriage bear-' ings and cooperates with the escapement mechanism at such point and likewise avoids side or cross strains on the bearings; that the carriage retarding device is likewise brought into cooperation with the carriage between its bearings so that the resistance offered by said retarding device does not offer or cause. any side or lateral strains to be exerted on the carriage hearing but exerts its resistance substantially in line with the pull on the carriage.

Various changes may be made without departing from the spirit and scope of my invention.

What I claim as new and desire to secure said independent reed ars with the machine and for holding them against accidental displacement thereon.
